The following GPS coordinates will locate where JB, Neal, & David are sleeping tonight at the CDT southern terminus on the U.S./Mexican border (copy & paste in Google maps, etc):
+31° 29' 42.62", -108° 12' 31.09"
To get to the terminus, they had to drive 28 miles of very rough desert road that, in David's words, "seemed to go on & on". When they arrived around 6:00 PM, the temperature was 103 degrees. David mentioned as they were setting up camp, several Mexican border patrols rode by in camouflaged Jeeps, with plenty of weaponry.
